>>3726048>Can I crop a picture free hand or is it retarded?Sure? Like as opposed to using a ruler when cropping? It doesn't really matter. Just cut out what you don't like or get the horizon and lines lined up.
>Also how do I know my pics are correctly exposed? I learned yesterday that the histogram is about jpeg and not raw files.Uh...the histogram is very important in the raw files where you can adjust exposure. What are you using? Lightroom? The histogram is just a measure of your light. Something on the right is usually too bright, and something on the left is too dark. Generally you wanna keep things spread out in the middle but that's not a hard rule. For example if you were shooting fireworks at night, you will see a lot of black so it will heavily be on the left.
>Last question: is there a "sunny 16 rule" but for DSLR? I tried it yesterday and photos where correctly exposed at 1/100 f8 100iso (sunny day).Why not use the exposure meter in the camera?
